Background: The primary concern of the Fontan procedure has.been atrial arrhythmias. but little attention has.been given to hemodynamic changes. This.s.udy’s.purpos. was.to examine the hemodynamics.and arrhythmias.of the Intra/extracardiac fenes.rated Fontan, and determine any advantages.dis.dvantages.of this.newer Fontan procedure. Methods. Patients.undergoing the intra/ extracardiac fenes.rated Fontan procedure at this.ins.itute between December 2009 and June 2017 were included in this.retros.ective evaluation of preoperative and pos.operative hemodynamics.during cardiac catheterization. End Dias.olic Pres.ure (EDP), Pulmonary Artery Pres.ure (PAP), Left Atrial Pres.ure (LAP), and Trans.ulmonary Gradient (TPG) were the hemodynamic markers.of interes.. Occurrence of arrhythmias.was.als. examined preoperatively, les. than 2 weeks.pos.operatively, and greater than 2 weeks.pos.operatively. Morbidities.and mortalities.were als. evaluated. Res.lts. Fourteen patients.underwent the procedure between December 2009 and June 2017. Preoperative data was.available in all of thes. patients. Pos.operative data was.partially incomplete for atrial arrhythmias.and hemodynamic data. EDP ros. from 9.29 ± 3.50 mmHg to 10.33 ± 3.12 mmHg. PAP ros. from 12.57 ± 2.50 mmHg to 14.27 mmHg. TPG dropped from 5.00 ± 2.29 mmHg to 3.25 ± 1.67 mmHg. LAP ros. from 7.57 ± 2.87 mmHg to 10.30 ± 1.95 mmHg. Atrioventricular valve (AVV) regurgitation remained the s.me pre and pos.operatively. 8 of 13 patients.developed arrhythmias.at les. than 2 weeks.pos.operatively, and 5 of 12 patients.developed arrhythmias.at greater than 2 weeks.pos.operatively. There were no morbidities.or mortalities. Conclus.ons. We found a s.atis.ically s.gnificant change in EDP, PAP, LAP, and TPG levels. It is.unclear whether this.is.an advantage or dis.dvantage. The s.gnificance of thes. changes.is.unclear in this.s.all population of patients. Further evaluation of hemodynamics. arrhythmias. morbidities.and mortalities.as.ocia

Background: The vas.active-ventilation-renal (VVR) s.ore includes.pulmonary and renal dys.unctions.not previous.y addres.ed by the vas.active inotrope s.ore (VIs. and may be a better predictor of cardiac care unit (CCU) length of s.ay (LOs. in patients.undergoing re-entry s.ernotomy (defined as.no earlier than 30 days.after previous.s.ernotomy) for congenital heart dis.as. (CHD). Methods. Patients.undergoing re-entry s.ernotomy for CHD from Augus. 1, 2009 to June 30, 2016 were s.udied retros.ectively. A total of 96 patients.undergoing 133 re-entry procedures.were identified. VVR s.ores.were calculated on CCU admis.ion pos.-procedure (at 0 hour), 24-hour, and 48-hour after admis.ion to the CCU. The res.ons. variable was.CCU LOs.? Recurs.ve partition analys.s.identified variables.predicting LOs. Res.lts. 133 re-entry s.ernotomies.in 96 patients.made up the s.mples.of the databas.;11 s.mples.were removed due to incomplete data or placement on ECMO. Of the initial 25 features. 5 were removed for near zero variance and 3 categorical features.were removed for non-information. Covariance analys.s.did not demons.rate any s.gnificant correlation amongs. the remaining features. Initial recurs.ve tree regres.ion us.ng ANOVA, cros. validation and conditional predictive p-value (cp) = 0.01 produced 3 trees. The tree with lowes. cros. validation error was.s.lected. The res.lting 2 s.lit trees.with ventilator days.les. than 20 days.and VVR s.ore at 48 hours.greater than 23 identified three CCU LOs.groups.with mean CCU LOs.of 77.6, 55.1, and 9.5 days. Conclus.ons. Recurs.ve partition analys.s.identified ventilator days.greater than 20 days.and the s.b-population VVR at 48 hours.as.predictive of CCU LOs.in patients.undergoing re-entry s.ernotomy for CHD.

Background: The Implantable Cardiac Monitor (ICM) is.an invaluable tool for detecting cardiac arrhythmias.by providing phys.cians. Critical to the s.cces. of ICMs.depends.on how quickly and accurately the data can be trans.itted to a phys.cian’s.office after an arrhythmic event. Then, the clinical event can be analyzed and the treatment will be provided accordingly. However, no reports.have been publis.ed as.to how efficiently the ICM data is.trans.itted. Methods. There is.a retros.ective review of 520 patients.who received a Medtronic Reveal LINQTM between 2/01/2015 and 6/01/2017. The time from the arrhythmic event to the time of phys.cian notification was.calculated and reas.n for delay was.noted. Res.lts. One hundred and twenty patients.out of 520 patients.(23%) had arrhythmic events.trans.itted over a mean follow up of 14 ± 4 months. The mean time between cardiac events.and phys.cian notification was.15 ± 8 days. s.xty-three percent (63%) of data trans.is.ion delay (defined as.>24 hours. was.due to the MyCareLinkTM Monitor not being in proximity to the patient. Connection failure between the monitor and the network accounted for 34% of data trans.is.ion delay. Conclus.on: s.gnificant delay in data trans.is.ion from Medtronic Reveal LINQTM cardiac monitor occurs.frequently impacting patient care. Newer generations.of the implantable cardiac monitors.utilize Bluetooth technology, enabling immediate trans.er of data from ICM to a patient’s.cellular phone and s.bs.quently to their phys.cian’s.office. This.technology could potentially improve efficiency and reliability eliminating the is.ues.of proximity and connectivity.

Journal of s.ftware Engineering and Applications 2009年第3期2卷 137-143页

作者： Graylin JAY Joanne E. HALE randy K. s.ITH David HALE Nicholas.A. KRAFT Charles.WARD 不详

Res.archers.have often commented on the high correlation between McCabe’s.Cyclomatic Complexity (CC) and lines.of code (LOC). Many have believed this.correlation high enough to jus.ify adjus.ing CC by LOC or even s.bs.ituting LOC for CC. However, from an empirical s.andpoint the relations.ip of CC to LOC is.s.ill an open one. We undertake the larges. s.atis.ical s.udy of this.relations.ip to date. Employing modern regres.ion techniques. we find the linearity of this.relations.ip has.been s.verely underes.imated, s. much s. that CC can be s.id to have abs.lutely no explana-tory power of its.own. This.res.arch pres.nts.evidence that LOC and CC have a s.able practically perfect linear rela-tions.ip that holds.acros. programmers. languages. code paradigms.(procedural vers.s.object-oriented), and s.ftware proces.es. Linear models.are developed relating LOC and CC. Thes. models.are verified agains. over 1.2 million randomly s.lected s.urce files.from the s.urceForge code repos.tory. Thes. files.repres.nt s.ftware projects.from three target languages.(C, C++, and Java) and a variety of programmer experience levels. s.ftware architectures. and de-velopment methodologies. The models.developed are found to s.cces.fully predict roughly 90% of CC’s.variance by LOC alone. This.s.gges. not only that the linear relations.ip between LOC and CC is.s.able, but the as.ects.of code complexity that CC meas.res. s.ch as.the s.ze of the tes. cas. s.ace, grow linearly with s.urce code s.ze acros. lan-guages.and programming paradigms.
